Does C or C++ have a standard regex library?

Question

Does it? If yes, where can I get the documentation for it... if not, then which would be the best alternative?

Answer 1

If by standard you mean bundled with compiler, then not. But most of the other languages that bundle regex extension use pretty standard c implementations. E.g. PCRE - Perl Compatible Regular Expression and C libraries have POSIX regex support (see man page).
